Abstract: Predictive queue flushing for real-time synchronization of data sets between two data stores, comprising a data synchronization software module that interfaces with each data store, and uses a queue monitor to record and store changes to data on each data store and calculate velocity and acceleration of event arrivals, and a policy manager to manage synchronization, and a query generator to incorporate policies from the policy manager and measurements from the queue monitor to direct the data synchronization software module, flushing the change queue in accordance with the established synchronization policy, yielding synchronized shared data sets.

Abstract: Real-time synchronization of data between disparate cloud data sources; local database receives data from various sources then supplies data to various destinations. A steady state database synchronization software module monitors local database for changes to data, reconciles any local change with changes to the same data in remote database, forwards reconciled data to a destination database, and monitors messages announcing that data in remote database has changed. Finally, the failsafe database synchronization software module polls the remote database periodically for changes, compares changes made to remote data and local data, outstanding changes are applied to local and remote databases as determined.
